B. JSON



WHAT IS JSON?

    JSON is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute-value pairs and arrays. It is a very common data format, with a diverse range of applications, one example being web applications that communicate with a server.

WHAT IS AJAX?

    AJAX is a set of web development techniques using many web technologies on the client side to create asynchronous web applications. With AJAX, web applications can send and retrieve data from a server asynchronously without interfering with the display and behavior of the existing page.
